CHURN.

SIEGIFICATION forming part of Letters Patent No. 423,710, dated March 18,1890.

Application filed December 7, 1889- Serial No. 332,877. (No model.) v

To all whom, it may concern:

Be it known that I, JOHN ANDREW ADAMS, of Salyersville, in the county of Magoflin and State of Kentucky, have invented certain new and useful Improvements in Ohurns; and I do hereby declare the following to be a full, clear, and exact description of the invention,

such as willenable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

Hy invention relates to an improvement in churns; and it consists in the combination and arrangement of parts, which will be more fully described hereinafter, and particularly pointed out in the claim.

The objectof my invention is to provide a means by which the cord which passes around and operates the dasher can be tightened from time to time.

Figure l is a side elevation of a churn which embodies my invention. Fig. 2 is a plan view of the same. Fig. 3 is a detached view of the adjusting device and the slide alone.

The supporting-frame consists of the sill A, the two standards B, mounted thereon, and

the cross-piece O, which connects the upper ends of the standards together and forms a support for the operating parts. Placed upon the top of this support 0 are the two guides or ways D, between which the slide F is placed. This slide is here shown as being made triangular in cross-section; but it may be given any other form that may be preferred. Journaled upon the outer end of this slide is the operating-wheel G, to which the lever or handle H is rigidly secured, and by means of which the wheel is turned, first in one direction and then in the other, as far as the stops L on its under side will permit. These stops alternately strike against the ends of the guides or ways, and thus prevent the wheel from being turned beyond a certain distance. Secured to this wheel and passing around the upper end of the dasher I is a cord or band J, by means of which the dasher is made to rotate first in one direction Owing to the amount and then in the other.

of moisture in the air this cord or band contracts and lengthens, and the consequence is that at one time the band will operate the dasher and at another time it will not, owing to the fact that the band becomes so slack that it will not exert sufficient frictional contact upon the dasher to both hold it in position against its bearings and rotate it at the same time. The consequence is it becomes necessary to provide a means for lengthening and shortening the band, and for this purpose the hinged or otherwise movable adjusting device 0 is used. This device is hinged to the block P, which is secured upon the top of the part 0 and forms bearings for the inner end of the slide. A number of stops or shoulders are formed upon the inner end of this adjusting device, and the slide is adj usted in or out, so that its end will bear against one or the other of the shoulders, according as the cord or band is slack or taut. By means of this adjusting device the cord can be tightened or slackened in a moment, as may be necessary.

The one great trouble with this form of vibrating churn heretofore has been that the band or cord would become either too tight or too loose to have the churn work satisfactorily. By the addition of a tightening device, as here shown, and placing the operating-wheel upon a slide this trouble is entirely overcome.

Having thus described my invention, I claim- The combination of a suitable supporting frame, the guides or ways placed upon its top, the endwise-movable slide, the operatingwheel j ournaled upon its top, the cord or band secured to the wheel, the churn-dasher, and

the adjusting device which engages the inner end of the slide and frame, by means of which ghe hslide is adjusted, substantially as set ort In testimony whereof I affix my signature in presence of two witnesses.

JOHN ANDREW ADAMS.
